Ok heres the deal: computer wouldnt get past the welcome screen, it would just lock up totally. nothing new was installed or deleted, no hardware changes either. First thought my hdd was corrupted but tested just perfect on another computer. Than thought maybe motherboard was screwed up somehow.......so I ordered another motherboard......than played around with the FSB and lowered it from 133 to 100 and now everything runs fine......Now I'm thinking it's the chip because it still runs as hot as it did when it ran at 133. Im probably ordering a new chip too anyway. Any ideas what could be wrong? Oh yea the highest FSB I can raise it to before it gets all nuts on me is 120.
